You used one of the Japanese BIOSes? From the title, I can see that that would be the only BIOS the game works with. Should be the default, but worth a look to check.

was worth a shot but bioses 1 through 10 or bios japan dont work, most give 153500 3rd round loss result, one gives a result that loses in the 2nd match instead of 3rd, and a couple others say they wont work with that country's bios.

If you're getting any game at all, then you are using a japanese BIOS for sure. It will not start up with a non-japanese BIOS (damn region locking).

No BIOS is obviously marked as the default, so I presume that -bios 0 is the default (or -bios jp). There are 4 japanese BIOS all up (0 to 3).
Also, there's the debug (7) and dev[elopement] (8) BIOSes, which I'd guess would run the game too.

I would also highly recommend that newer versions of MAME be used for ST-V games. More likely to work properly.

153,500 for me too ;
probably RTDSC stuff cause the desync

the bios is the default one (should be japan epr19730)

I had some issues with playbacks too, but eventually worked out... it desynchs a little sometimes and on the long range it makes the whole go off... (even though the desynched could win a bit more before XD)
the fact is that is game is quite heavy and i played it with auto frameskip, which i realize now that wasn't a great thing...
maybe it better if i make a new inp, shouldn't be a heavy work :)

edit: forgot to say, when it didn't work i used throttle, when i didn't it worked ;)

I just played it back four times in a row, same settings, same everything. The result was four different scores:

466K
608K (Yep, this is the advertised score)
153K
150K

All the time without frameskip, no throttling, no pausing. I guess there is a random element lurking somewhere.

Real Time Clock,RTC for the friends. :wink:

(Lines from 622 of stv.c)

Code: Select all

/*"Interrupt Back"*/
case 0x10:
	if(LOG_SMPC) logerror ("SMPC: Status Acquire\n");
	smpc_ram[0x5f]=0x10;
	smpc_ram[0x21] = (0x80) | ((NMI_reset & 1) << 6);
	smpc_ram[0x23] = DectoBCD(systime.local_time.year /100);
	smpc_ram[0x25] = DectoBCD(systime.local_time.year %100);
	smpc_ram[0x27] = (systime.local_time.weekday << 4) | (systime.local_time.month+1);
	smpc_ram[0x29] = DectoBCD(systime.local_time.mday);
	smpc_ram[0x2b] = DectoBCD(systime.local_time.hour);
	smpc_ram[0x2d] = DectoBCD(systime.local_time.minute);
	smpc_ram[0x2f] = DectoBCD(systime.local_time.second);
MAME-wise,there's an implementation of the RTC get time/save time that gets into the record/playback .inps in 0.128...It's really likely that in MAME 0.106 that feature is missing.

Didn't know that :(

I think it's advised to add a Special Rule "WolfMAME v128 or higher requested for inps" or similar (if 128 was the first with RTC)

I'm pretty sure that I had a workaround for the ST-V RTC in wolf106... will check later.

First we need more testing ; could you make another inp with wolf128 (and attached there if lower) so that we can check if it playbacks ?

hmm, i don't think that's the problem. Since i think i also have the old wolf106 roms too because i don't get an error when playing back. DeFrenZ, a question: can you play this game back yourself to the score you posted?
